sphere()

Draws a surf plot of an 20-by-20 sphere in the current figure.

Returns 1. entry

Arguments

Example

[X, Y, Z] = sphere()

Returns the three matrices with x-, y-, and Z coordinates for a unit sphere. The matrices are saved in the variables X, Y, Z.

sphere(n)

Draws a surf plot of an n-by-n sphere in the current figure.

Argument n

Scalar

Returns 1. entry

Arguments

Example

[X, Y, Z] = sphere(30)

Returns the three matrices with x-, y-, and Z coordinates for a unit sphere with n = 30. The 31x31 matrices are saved in the variables X, Y, Z.
